Seagate ST9816AG Compatibility notes

Compatibility notes

•The Marathon 810 conforms to the ATA interface specifica-

tions. The host system BIOS must provide suppor t for the ATA

interface command set. For a detailed description of the ATA

commands implemented by this drive, see the

and the

•In accordance with ATA specifications, the system BIOS must

reset any emulation/translation paramete rs after a hard reset.

•In some configurations, a Marathon 810 may supply up to 16

bytes of error-correction code (ECC) with the Read Long and

Write Long commands. Depending on the drive type, your

system BIOS may look for 4 bytes of ECC. If your system

BIOS expects 4 bytes of ECC and the drive supplies a different

number of bytes, some drive diagnostic programs may fail,

typically resulting in time-out errors. Consult your computer

documentation or call your computer dealer or manufacturer

for information on configuring your computer to receive more

than 4 bytes of ECC.

•Some older drive diagnostic programs may incorrectly report

an ECC-detection failure when analyzing a Marathon 810.

This occurs because the drive hardware corrects the data

automatically, avoiding the error rather than repor ting it. Su ch

a report does not indicate a drive malfunction.
